SPRINGFIELD -- Pioneer Valley Transit Authority bus riders will pay 20 percent more at the fare box and for passes and paratransit trips starting July 1 following a vote Monday of the the PVTA Advisory Board.

The board also voted Monday to take a once-every-three-years review of its fares, which before Monday hadn't gone up in a decade. But any fare hikes resulting from those reviews would need a new set of public hearings and a vote at that time.

Level funding from the state for the PVTA means the agency gets $23.6 million in the coming budget year. Rising costs for buses, fuel, maintenance and payroll would leave the transit agency with a $3.1 million budget gap, according to the PVTA.

The board also adopted a series of service cutbacks, but delayed the implementation of those cutbacks until the end of September with the hopes that PVTA could get an additional $2.5 million from the state in the new budget that won't be approved until just before the state fiscal year ends on June 30.

"We are doing this in the hopes that we will be able to rescind the cuts," said Brian O'Leary, a board member representing Belchertown.

But he said the board needed to vote on the cuts -- which might be needed to close a budget gap -- because the cuts have already been published for public comment and hearings have been held. The board couldn't wait until after the state budget for the vote it took Monday because it would have had to have those hearings and public comment periods all over again, O'Leary said.

PVTA administrator Sandra Sheehan said delaying the route cutbacks still gives drivers time to bid, based on seniority, for the routes they wish to drive. That bidding process can take place after the state budget is final and before the route changes.

With a 20 percent increase, a basic one-way fare would rise from $1.25 to $1.50. The 25 percent fare hike PVTA staff members had asked for would have made that fare $1.60.

Also approved Monday were a list of service cutbacks. The cutbacks are, like the fare increase, not as drastic as first announced months ago. (The latest proposal is detailed in the documents below, both with mitigation plans and organized by route number.)

If approved by the board, changes would take effect in May and June.

If the state legislature increases the $80 million Gov. Charlie Baker included in his budget for the state's 15 Regional Transit Authorities, The PVTA would get an additional $2.5 million for the fiscal year.

That coupled with $500,000 in additional money from the fare increase and some help form the state on capital purchases would close the budget gap, the Board was told.
